' SPECIFICATION forming part of Letters Patent No. 527,137, datedOctober 9, 1894. Application filed February V8, 1894. Serial No.4991503- (NO IDOBL) To all whom/it may concern v Be it known that I, JEREMIAn CLAYPOOL, a citizen of the UnitedStates, residing at Marshall,in the county of Clark and State ofv Illinois, have invented certain newand useful Improvements in Window or-Sa'sh-Locks; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled inv the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to theletters of reference marked thereon,which form part of this specification.

My invention relates to an improved sash lock, in which an eccentricallysuspended cylinder is embedded in the window-frame,

immediately behind the edge of the windowsash, and in'such position thatthe cylinder may be thrown against the edge of the Window-sash; in whichposition it will bind, or hold the sash; or away from the sash, thusliberating the sash.

-The objects of my invention are, tirst, to provide a lock which will bestrong, durable and cheap; second, to provide a lock which will do awaywith the necessity of window cords and weights; third, to provide Aa`lock whose efficiency will not be aiected by the wearing away of theIwindow-sash, shrinkage, change of temperature, &c., and last to pro-vvide a lock which can be easily and conveniently operated by any one,andone which can not get out of order. I attain these objects by meansof the mechanism illustrated in the accompanying drawings, in which-Figure -1, is a perspective view of an upper corner of a window frameand sash, portions of each of which are cut away, for the purpose ofshowing the lock in position. Fig. 2 is a detailed'view in perspective,of the lock itself and of its parts. y

Similar letters of reference refer to similar parts throughout bothviews.

Fig. 2 of the drawings,- represents a lock which consists of a cylindera, of brass, iron or any other suitable material, a strong metal shaft band a handle,^or knob h. About two thirds of the longitudinal section ofthe cylinder a., is hollow, and the remaining third section is solid, asshown in Fig. 2.

The lettere indicates a square groove which iscutintothe face of theinner wall of the solid section ofthe cylinder, parallel with the v axisofthe cylinderand for the purpose of The hollow portion of the cylinderis filled up with wood,` or any other suitable light material, which Iindicate bythe letter d. Between lthe filling d and the inner face ofthe Solid portion bf the cylinder, indicated by 0, I placca steel platefr', which clamps thev shaft b, tightly Within the groove c, andvprevents the wood or other tllingd from wearing away and becomingloosened. Thus the cylinder a is mounted upon itsshaft eccentrically andacts as an eccentric. The end e of the shaft b, which passes through thecylinder a, protrudes from and `beyond the end of the same, and saidprotruding end is rounded and rests in a bearing within thewindow-frame. A short section of the other endof the shaft b, is bent ata point indicated by the .letter b', at a right angle to the shaftproper, in order that it may inserted within a slot, or groove f whichis out into the face g of the base ofthe knob, or handle h.

To further secure the handle, or knob h, to the shaft b I solder thesame into the groove f.

The handle, or knob h, which may be of any convenient material and form,serves as a balance to the eccentric cylinder, as well as a means ofoperating the invention, as hereinafter fully described and explained.

To attach my invention toa window, I simply cut'a recess in thewindow-frame, large enough to receive the cylinder a, and to give thesame,-room to revolve in. vSaid recess being immediately behind the edgeofthe window sash, and invsuch close proximity that vwhen the largerside of the eccentric cylinder a, is turned toward the sash, it willbind against the same. I then drill a straight passage, through thewindow-frame to and vbeyond the recess in order that the shaft bmay bepassed through said passage, and lind a bearing for its protruding ende, in the inner part of 'the window-frame.

Having thus prepared the window-frame,-

I place the eccentric cylinder a, within the recess m; in suchposition,` that the groove c, which passes through the cylinder a, willform, with the passage drilled through the window- IOO frame, acontinuous passaage, through which I pass theshaft b. Thus the cylinderissus-v pended within the recess m, and is easily revolved to anyrequired position by means of the handle h, which is placed upon theouter end of the shaft b. Y u, l

I find it most convenient, in attaching my lock to a window, to so hangthe eccentric cylinder, that the larger side of the same, will naturallyhang upon the side of the recess opposite from the edge of thewindowsash; and to soadjust the shaft b, that when it is driven firmlyinto and through the cylinder, the bent end of the same' will natrirallystand perpendicularly upward from l of friction with the same.

To lower the sash it is only necessary to 'turn the knob h away from theWindow, 3o thereby relieving the pressure'from the edge of the sash.

'Yhen the sash is down,or closed, I turn the knob h away from thewindow, thus throwing the larger. side of the `eccentric cylinder belowcenters, and against the edge of the sash, in which position any effortto raise the sash, will by friction, tend to turn the cylinder upwardand toward the sash, thus locking' the sash more firmly.

vHaving described my invention and its use, what I claim, and desire tosecure by Letters Patent, is- Y The combination, in a window-sash andwindowframe,with a, cyli-ndera, suspended '45 eccentrically within arecess ai, said cylinder being provided with a wood, or other suitablefillinf'.: d, the metallic' plate i, and the groove c, a shaft b and ahandle, or knob z; all substantially as and for the purposes set; forthand described.

In testimony'r that I claim the foregoing as my own I aiix my signaturein presence of two witnesses.`
